Set the trigger to be the channel with the bit-clock.

Pressing Show Measures will display the number of samples on the display (Compares) and the number of
Violations of the mask regions. This is a toggle, and pressing it again will turn off those values.
Press Zoom to Eye to automatically place the mask in the display. To change the mask position or size, press
